Fulham owner Shahid Khan as revealed his plans to install a roof at Wembley.
The billionaire has reportedly lodged a £1billion bid to buy the stadium from the English FA.
England's national stadium had a partial roof installed between 2003 and 2007, but Khan wants to see something more permanent.
"There are now all kinds of plastic roofs [you can install], so if you could do that you could control the climate," Khan told the Daily Telegraph.
"With the roof there are two sliding parts that move but the rain can still come in and if you are looking at a winter concert, for example, would it be comfortable for people?"
